My 16-month theanine self-experiment

For a community that prides itself on critical thinking, I'm always surprised to see HN lap this sort of pseudoscientific witch-doctor stuff up.

This poorly-controlled, N=1 experiment tells you nothing, not even about the author.

There's absolutely no reason to consider these novice self-experiments when professional scientific experiments are available (unless you're hunting for a specific result).

The author directly quoted the European Food Safety Authority, who found the same thing he did. There's a rich history of self-experimentation in medicine and nutrition, I don't think you need to be so negative.
